Candidates commonly report scenario questions about delays or shortages, questions on the metrics they've owned and, for analyst and planning roles, some Excel or data work. What candidates commonly report; it varies by employer, level and country. Last reviewed 18 October 2026.

How did you measure the improvement? A good answer covers - The process and what was wrong with it - What you changed and how you got people to follow it - The before-and-after numbers ### Tell me about a time a shipment, supplier or delivery let you down at the last minute. What did you do? A good answer covers - What failed and who it affected - The quick fix you found and who you kept informed - What you changed so it was less likely to happen again ### Describe a time you had to manage a team or vendor that wasn't meeting expectations. A good answer covers - The gap, with facts rather than opinions - How you raised it and agreed what would change - The result, including any tough decision you made ### Tell me about a decision where you had to trade off cost against speed or service. A good answer covers - The options and what each would cost or save - How you decided and who you consulted - How it turned out and whether you'd choose the same again ## Questions about the job ### A key product is out of stock in several cities and customers are complaining. Walk me through your first day. A good answer covers - Containing it: what stock exists, where, and what can be moved quickly - Telling sales and support what to say to customers - Finding the cause: forecast, supplier, transport or system, and fixing it ### How would you decide how much safety stock to hold for an item? A good answer covers - How much demand varies and how long resupply takes - The service level the business wants against the cost of holding stock - Reviewing it as demand or lead times change ### Explain the difference between push and pull in a supply chain, with an example of each. A good answer covers - Push: making or moving stock based on a forecast - Pull: making or moving stock in response to actual orders - Where each fits, and how many businesses mix the two ### A warehouse keeps missing its same-day dispatch target. How would you find the bottleneck? A good answer covers - Mapping the steps: receiving, storing, picking, packing, dispatch - Measuring time and volume at each step to see where work piles up - Fixes such as layout, shift timing or batch picking, and checking that they worked ### How would you evaluate two suppliers for the same part and choose between them? A good answer covers - Total cost, not just unit price: freight, quality failures, payment terms - Reliability, capacity, quality records and references - Risk: depending on one supplier, and a back-up plan ### What does inventory turnover tell you, and what would you do if it's falling? A good answer covers - How many times stock is sold and replaced in a period - Falling turns can mean slow-moving stock, over-ordering or weaker demand - Actions: clearing old stock, better forecasts, smaller and more frequent orders ### How would you cut the cost per delivery for a local delivery network without making deliveries slower? A good answer covers - Where the cost goes: riders or drivers, vehicles, failed deliveries, idle time - Ideas such as better routing, batching orders and fewer failed attempts - Measuring cost and delivery time together during a trial ### What do lean ideas such as cutting waste or 5S look like in practice on a shop floor or in a warehouse? A good answer covers - Waste in plain words: waiting, extra movement, overproduction, defects - 5S as sort, set in order, shine, standardise and sustain, with an example - Keeping it going after the first clean-up ### How would you forecast demand for a new product with no sales history? A good answer covers - Using similar products, market data and early orders - A simple forecast with a range, not a single number - Updating it quickly as sales come in ### Which systems have you used, such as an ERP, a warehouse system or Excel, and what did you do in them? A good answer covers - The systems and the tasks you did in each - One report or analysis you built and how it was used - How you'd learn a new system quickly ## Motivation and fit ### Tell me about yourself and the operations work you've done so far. A good answer covers - Your background in two or three lines - The operations work you've done, with one result - Why this role is the next step ### Why operations? What do you enjoy about the work? A good answer covers - What draws you to it: solving problems, seeing results, working with people - An example that shows it - The area you want to grow in: planning, procurement, logistics or plant operations ### Operations roles can involve shifts, site visits and peak-season pressure. How do you feel about that? A good answer covers - An honest answer about your availability - An example of handling a busy or unpredictable period - How you stay organised when things change quickly ## Tips - Have numbers ready for what you've owned: on-time rates, cost savings, stock levels, error rates. - In scenarios, separate the short-term fix (keep customers served) from the fix for the root cause. - Freshers: an internship, a college event you ran or a family business can give you strong operations stories. - Learn the basics of an ERP and Excel (lookups, pivot tables); many operations roles use them every day. - Mention safety where it applies; on sites and in warehouses it matters as much as speed. - For procurement roles, prepare a negotiation story: what you asked for, what you gave up and the saving. ## Practise it out loud A mock interview asks what operations and supply chain interviews usually test, follows up on your answers and gives you a report.
